Bug#534936: pbuilder-buildpackage reinstalls fakeroot and breaks the build environment that way

[Andreas Beckmann]

Package: pbuilder
Version: 0.188
Severity: normal

Hi Junichi,

fakeroot in testing is currently broken (in respect to libc6-dev-i386
because of the /emul/ia32-linux/ transition in unstable), so I manually
downgraded it to the working version from stable in my squeeze builder
after the last update. Unfortunately pbuilder-buildpackage installs
fakeroot after satisfying the build dependencies causing an update of
the already installed version and breaking everything else (if
libc6-dev-i386 installed). If the reinstallation could be skipped if the
package is already present everything should work out fine.
fakeroot gets added to the EXTRAPACKAGES list at the beginning of
/usr/lib/pbuilder/pbuilder-buildpackage.

For now I will block the bad version in /etc/apt/preferences:

Package: fakeroot
Pin: release stable
Pin-Priority: 501

Unfortunately the following intuitive solution does not work (#454080):

Package: fakeroot
Pin: version 1.12.4
Pin-Priority: -1
